Product Description

Overview

Dual plate check valve is mainly composed of valve body, valve disc, valve seat, torsion spring, rotating shaft, etc. Its valve disc is composed of two semicircular valve discs. When it is opened, the two valve discs are folded together, and when closed, the valve disc forms a full circle. It closes faster than the single disc swing check valve.  


Features

1. It has a short structure length, which is only 1/4~1/8 of the traditional flange check valve;
2. It is small in size and light in weight, which is only 1/4~1/20 of the traditional flange check valve;
3. It has a fast closing speed and low water hammer pressure;
4. It can be used in both horizontal and vertical pipelines and is easy to install;
5. It has sensitive action and good sealing performance;
6. It has a short valve stroke and low water hammer;
